Spectral Asparagus

#81b72e
Notes

Spectral Asparagus (#81B72E) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (84°, 60%, 45%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Spectral
adjective

Latin spectrum, appearance — adjectival suffix -al. As a color modifier, spectral implies a saturated-and-rainbow-decomposed-and-pure quality, the bright color of Newton-prism sunlight-decomposed seven-color spectrum band. Sits at the bright-and-pure end of the grid, parallel to prismatic and pure in usage.

Asparagus
noun

Asparagus officinalis, the cultivated perennial whose tender spring shoots have been a delicacy since Mediterranean antiquity — Apicius gives a recipe in the first century. The color refers to the tip of a fresh asparagus spear: a soft, slightly yellow-shifted green with the matte finish of a young plant stem. Cooler than pear, warmer than sage, with the seasonal weight of a vegetable available only briefly each year.
